- Technical Service Instructions Re Drive System SI-6GRRE t General Safety Information WARNING The ST-M66/ST-M61/ST-M65 / ST-M60 DUAL CONTROL lever is used for both ge shifting and braking operations. Make sure that you fully understand and e accustomed to the ge shifting and braking operations for your bicycle. Refer to the illustration for the method of operation. Braking can only be performed with the DUAL CONTROL lever. If you use the ge shifting relee lever (Auxiliy relee lever) for braking, the relee lever may become damaged and you may lose control of the bicycle, which could result in an accident. If the internal unit of the DUAL CONTROL lever becomes damaged, the lever will move down from the normal lever position, and it may move to a position where braking is difficult to cry out. If this hpens, you should stop riding the bicycle immediately. Check that the wheels e ftened securely before riding the bicycle. If the wheels e loose in any way, they may come off the bicycle and serious injury may result. Use neutral detergent to clean the chain. Do not use alkali-sed or acid sed detergent such rust cleaners it may result in damage and/or failure of the chain. Use the reinforced connecting pin only for connecting the nrow type of chain. There e two different types of reinforced connecting pins available. Be sure to check the table below before selecting which pin to use. If connecting pins other than reinforced connecting pins e used, or if a reinforced connecting pin or tool which is not suitable for the type of chain is used, sufficient connection force may not be obtained, which could cause the chain to break or fall off. If it is necessy to adjust the length of the chain due to a change in the number of sprocket teeth, make the cut at some other place than the place where the chain h been joined using a reinforced connecting pin or an end pin. The chain will be damaged if it is cut at a place where it h been joined with a reinforced connecting pin or an end pin. Check that the tension of the chain is correct and that the chain is not damaged. If Chain tool the tension is too weak or the chain is damaged, the chain should be replaced. If this is not done, the chain may break and cause serious injury. Use a front chainwheel which is compatible with -speed chains in conjunction with Shimano CN-7701, CN-HG3 and CN-HG73 chains. If a chainwheel for an 8-speed chain or less is used, front chainwheel ge shifting problems may occur, or the chain pins might fall out, causing the chain to break. Obtain and read the service instructions cefully prior to installing the pts. Loose, worn, or damaged pts may cause injury to the rider. We strongly recommend only using genuine Shimano replacement pts. Read these Technical Service Instructions cefully, and keep them in a safe place for later reference.

If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur. You should periodically clean the derailleur and lubricate all moving pts (mechanism and pulleys). If ge shifting adjustment cannot be cried out, check the degree of pallelism at the re end of the bicycle. Also check if the cable is lubricated and if the outer cing is too long or too short. If you he abnormal noise a result of looseness in a pulley, you should replace the pulley. If the wheel becomes stiff and difficult to turn, you should lubricate it with gree. Do not ply any lubricant to the inside of the hub, otherwise the gree will come out. You should periodically wh the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain. If the chain keeps coming off the sprockets during use, replace the sprockets and the chain. When the chain is in the position shown in the illustration, the chain may sag, Shift the chain onto the next-lger re sprocket or the one after. Adjust the RD-M60 reverse spring type re derailleur from the low side. Use a frame with internal cable routing is strongly discouraged it h tendencies to impair the SIS shifting function due to its high cable resistance. Always be sure to use the sprocket set being the same group mks. Never use in combination with a sprocket being a different group mk. Use an outer cing which still h some length to spe even when the handlers e turned all the way to both sides. Furthermore, check that the shifting lever does not touch the bicycle frame when the handlers e turned all the way. Make sure that the ge shifting cable and the brake cable do not obstruct each other during braking operations. If they do obstruct, it may interfere with braking. Install the cables so that they still have some slack in them even when the handlers e turned fully in either direction.

A special gree is used for the ge shifting cable (SIS-SP41). Do not use DURA-ACE gree or other types of gree, otherwise they may cause deterioration in ge shifting performance. Gree the inner cable and the inside of the outer cing before use to ensure that they slide properly. For smooth operation, use the specified outer cing and the bottom bracket cable guide. Operation of the levers related to ge shifting should be made only when the front chainwheel is turning. If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the pltic pts of the shifting lever, this may cause the pltic pts to crack or become discolored. Therefore, you should make sure that the brake fluid does not adhere to these pltic pts. The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to pltic pts, but such pts should be cleaned with alcohol beforehand to prevent foreign pticles from adhering. Pts e not guanteed against natural we or deterioration resulting from normal use. For maximum performance we highly recommend Shimano lubricants and maintenance products For any questions regding methods of installation, adjustment, maintenance or operation, plee contact a professional bicycle dealer. In order to realize the best performance, we recommend that the following combination be used.

How to use the B-tension adjustment screw Mount the chain on the smallest chainring and the lgest sprocket, and turn the crank m ckwd. Then turn the B-tension adjustment screw to adjust the guide pulley close to the 2 sprocket possible but not so close that it touches. Next, set the chain to the smallest sprocket and repeat the above to make sure that the pulley does not touch the sprocket. 1 Lgest sprocket 2 1 Smallest sprocket B-tension adjustment screw
5. SIS Adjustment Push lever while turning the crank m to move the derailleur to the lgest sprocket. Then operate lever once to move the derailleur to the 2nd-ge sprocket. After this, operate lever just f the extent of play, and then turn the crank m. When changing to 3rd 23 When no noise is hed at all 23 Adjustment bolt 23 Adjustment bolt 23 Turn the cable adjustment bolt clockwise to tighten it until the chain returns to the 2nd sprocket. * Turn the adjustment bolt together with the outer cing adjustment rrel cover. Turn the cable adjustment bolt counterclockwise to loosen it until the chain touches a sprocket and generates noise. * Turn the adjustment bolt together with the outer cing adjustment rrel cover. Best setting The best setting is when the cable adjustment bolt is tightened (turned clockwise) until noise occurs without lever being operated, and then loosened (turned counterclockwise) 0-180 degrees from that point. Operate lever to change ges, and check that no noise occurs in any of the ge positions. For the best SIS performance, periodically lubricate all power-transmission pts. Replacement of the freewheel body After removing the hub axle, remove the freewheel body fixing bolt (inside the freewheel body), and then replace the freewheel body.
